If your going to be using the device primarily for e-mail/messaging, go with the Tour.
I have a Storm (provided by work), and unfortunately it's a pain for e-mails/messaging (I'm running the latest OS, updating did not significantly improve performance for me). I have tried Storm 2s as well, and although the touchscreen was improved it is still unacceptable for me/my use.
I would agree that's the Storm models are a failed experiment, a weak attempt to cut into the iPhone market share. RIM should stick to what they do best IMHO.
Just my $.02.
